Refractory bricks in a torpedo car used for hauling molten iron. In materials science, a refractory (or refractory material) is a material that is resistant to decomposition by heat or chemical attack and that retains its strength and rigidity at high temperatures. [1]
Ultra-high-temperature ceramics (UHTCs) are a type of refractory ceramics that can withstand extremely high temperatures without degrading, often above 2,000 °C. [1] They also often have high thermal conductivities and are highly resistant to thermal shock, meaning they can withstand sudden and extreme changes in temperature without cracking or breaking.
In 2003, Toshiba Ceramics sold its 51% stake in the company to NEG (40%) and Saint-Gobain (11%) and the company was renamed Saint-Gobain TM K.K. [10] The company specializes in producing fused cast products and serves the Japanese and more generally the Asian glass markets, employing around 200 people.The plant in Kozaki, Japan, covers 80,000 m ...
The European Commission funded a research project, C 3 HARME, under the NMP-19-2015 call of Framework Programmes for Research and Technological Development in 2016-2020 for the design, manufacturing and testing of a new class of ultra-refractory ceramic matrix composites reinforced with silicon carbide fibers and Carbon fibers suitable for applications in severe aerospace environments.
Calderys, a subsidiary of Imerys, is a multinational company specialized in producing heat resistant monolithic refractory products. [1] Calderys is headquartered at Issy-Les-Moulineaux on the outskirts of Paris, with over 2,000 employees and 18 plants in more than 30 countries.
Alumino silicate wool, also known as refractory ceramic fiber (RCF), consists of amorphous fibers produced by melting a combination of aluminum oxide (Al 2 O 3) and silicon dioxide (SiO 2), usually in a weight ratio 50:50 (see also VDI 3469 Parts 1 and 5, [7] as well as TRGS 521). Products made of alumino silicate wool are generally used at ...
CUMI-1954. CUMI was established as a result of diversification from banking business through cycle manufacturing with the intent to manufacture abrasive materials.CUMI's parent company, the Murugappa Group, made a tie up with the Carborundum, UK, a subsidiary of American abrasive manufacturer, Carborundum, USA and the Universal Grinding Co. Ltd., UK in 1950.
A German American, Emil Winter, acquired the mining rights and founded the "Austro-American Magnesite Company" (later Radex Austria). [3] In 1974 the company was bought by National Refractories Co. and in 1987 Radex-Heraklith Industriebeteiligungs AG ('RHI AG') emerged from the National Refractories Co. as a result of a management buyout.
